Hw 130 Motor Control Shield For Arduino Datasheet

void loop() // Ramp up speed from 0 to 255 for (int speed = 0; speed <= 255; speed++) analogWrite(ENA, speed); analogWrite(ENB, speed); delay(10);

: This IC expands the Arduino's digital pins. It converts serial data from just three Arduino pins into eight parallel outputs to control the direction of the L293D chips, preserving other Arduino pins for sensors or communication. Critical Specifications

Up to 2 hobby servo motors (5V high-resolution timers tied to Arduino pins 9 and 10) Pinout and Hardware Configuration

Two-pin screw terminals used to connect up to 4 bi-directional DC motors. hw 130 motor control shield for arduino datasheet

The HW-130 Motor Control Shield is an essential "bridge" for robotics. While it uses an older L293D architecture, its ease of use and compatibility with the Adafruit library make it the go-to choice for students and hobbyists building their first motorized creations.

3-pin header mapped directly to Arduino Digital Pin 10.

Cut that trace or remove the jumper immediately for high-voltage projects. void loop() // Ramp up speed from 0

Controlled via pins D3, D4, D5, D6, D7, D8, D11, and D12 . Servos: Connected to D9 (Servo 2) and D10 (Servo 1) .

Most sellers just repost a messy schematic or a photo of the board. But don’t worry—I’ve dug through the reference designs and reverse-engineered the logic. Here is what the unofficial datasheet actually means for your project.

The HW-130 shield uses two L293D motor driver ICs and one 74HCT595 shift register. This combination minimizes the number of Arduino pins required to drive your motors. 4.5V to 25V DC The HW-130 Motor Control Shield is an essential

Key specifications

Based on the pinout above, here is the truth table. To spin a motor, you set one direction pin HIGH and the other LOW . To brake, set both HIGH .

The servo headers route directly to the Arduino's hardware timers to ensure jitter-free control. Arduino Digital Pin 10 Servo 2: Arduino Digital Pin 9 2. Shift Register Pins (74HCT595)
